Should I use lime or cement mortar?
Pre-1920s homes with soft bricks must use lime mortar — cement mortar is too hard and damages the bricks. Modern homes can use cement mortar. Using the wrong type causes expensive damage.
Repointing replaces the deteriorated mortar between bricks, preventing water ingress and structural damage. Most UK homes built before 1990 will need repointing at some point. Costs depend on the area, height, and mortar type.
